What is Cold rolled?
Cold rolled is usually performed by longitudinal rolling. The process of cold rolling production generally includes raw material preparation, pickling, rolling, degreasing, annealing (heat treatment), finishing and so on. Cold rolling uses hot rolled products as raw materials, and the raw materials must be dephosphorized before cold rolling to ensure the surface of the cold rolled products is clean. Rolling is the main process of deforming the material. The purpose of degreasing is to remove the lubricating grease attached to the rolling material during rolling, so as not to contaminate the surface of the steel during annealing, and to prevent carbon addition to stainless steel. Annealing includes intermediate annealing and heat treatment of the finished product. The intermediate annealing is to eliminate the work hardening caused by cold deformation through recrystallization to restore the plasticity of the material and reduce the deformation resistance of the metal. The purpose of the heat treatment of the finished product is to eliminate hardening by recrystallization. It is also based on the technical requirements of the product to obtain the required organization (such as various textures, etc.) and product performance (such as deep drawing, electromagnetic performance, etc.). Finishing includes inspection, cutting, straightening (flattening), printing, sorting and packaging. Cold rolled products have high packaging requirements to prevent the surface of the product from being scratched during transportation.
